SPI+GPDMA Configuration

[OrionJ]

 

Besides, I don't know whether this configuration of MX is correct.

 /* Initialize all configured peripherals */
 MX_GPIO_Init();
 MX_GPDMA1_Init();
 MX_SPI2_Init();
 MX_ICACHE_Init();
 MX_I2C1_Init();
 MX_RTC_Init();
 /* USER CODE BEGIN 2 */
HAL_I2C_MspInit(&hi2c1);
HAL_SPI_MspInit(&hspi2);
HAL_RTC_MspInit(&hrtc);

Hello @OrionJ;

 

The configuration depends on your requirement.

Could you give more detail about your project context and requirement?

May SPI_FullDuplex_ComDMA_Master example can help you. This example explains how to handle an SPI as a Master to perform a data buffer transmission/reception between two boards, using DMA.

 

Thank you.
